Heaven’s stairs - Tian Men Shan, China

Tianmen (“Heavenly Gate”) Mountain National Forest Park lies only 8 kilometers south of the city of Zhangjiajie.Being situated immediately next door to the city of Zhangjiajie, Tianmen Mountain has traditionally been perceived by the residents of Zhangjiajie as the very soul of the city, even if the Zhangjiajie area in general has in more recent years become much more strongly identified, at least by outsiders, with the strangely eroded block-and-obelisk landscapes of Wulingyuan Scenic Area.
Tianmen Mountain National Forest Park is characterized by large, limestone mountain tablelands with sheer cliffs and with a fair share of jagged peaks – albeit, clothed in verdure – though Tianmen Mountain lacks the freestanding obelisks of Wulingyuan. This is of course no coincidence, since the building blocks, as it were, of Tianmen Mountain are of limestone, so even at its most advanced stage of erosion, Tianmen Mountain will never produce a landscape that is similar to the eroded-mountain landscapes of Wulingyuan Scenic Area, whose building block material is sandstone, which exhibits an entirely different erosion pattern than that of limestone.
